The Marocchinate: Collective memory or transmission of beliefs?

The survey will include an information-based intervention. Half of subjects will receive a text about the Syrian refugee crisis, while the other half will receive a text about environmental problems. Historical events, as described in Ghidoni & Schindler (2025) have generated an additional treatment and control condition we exploit in the analysis.

The survey will include an information-based intervention. Half of subjects will receive a short text about the Syrian refugee crisis, while the other half will receive a short text about environmental problems. Respondents will additionally be separated into a treatment vs a control group depending on whether their municipality of residence was visited by French Moroccan troops during World War II. This is the variation used in Ghidoni & Schindler (2025)

The respondents will get asked several questions on their demographics, residence, as well as ancestral locations. We will ask several questions to assess the role of collective memory versus transmission of attitudes.

The survey will be administered by an online survey provider to a representative sample of the Italian population in the 6 regions of Italy we study: Abruzzo, Campania, Lazio, Molise, Tuscany, and Umbria.

Marocchinate is a term used to describe acts of mass sexual violence and killings attributed to Moroccan soldiers who fought for France during World War II. These troops were part of the French Army and fought alongside the Allies, who were working to free Italy from German occupation. Reports of widespread violence emerged as the troops advanced after key battles.

The analysis of these questions is described in more detail in the pre-analysis plan.

Randomization is done by Qualtrics, additionally the historical (quasi) randomization was done by some historical events as described in Ghidoni & Schindler (2015).

The randomization will occur at the respondent level. Additionally, for the historical variation, it occurs at the municipality level; a respondent's municipality of residence will hence determine their assignment.

No

n/a

3,000 respondents

Based on the randomization by Qualtrics, we will have 1,500 respondents in each information arm. We expect (based on municipality size) to have around 975 respondents from municipalities with FEC exposure and 2,025 from municipalities without FEC exposure. The de facto distribution will depend on the response rates of the sampled individuals.
